Dunlop TT100s are good in the wet and are appropriate period tyres (in K81 form) for both bikes. They are excellent handling tyres as well for "older" design frames, but the grippy compound gives less mileage than some other brands. I used K70s on my XS650s and Metzlers or Contis on my T500s back in the day.

I used to run Avon Azarros on a Ducati Monster I once owned - street and track. Then one track event in a tropical storm downpour at Barber MSP I switched to Michelin Pilot Power Road tires at lunch break. The improvement was like night and day difference. From then on I ran the Michelins.

On my F 650 for street use I run Metzeler Tourance due to the 19 inch front wheel. Decent on wet roads.

On my R 80 ST I currently have Avon Distanzias with good street results wet and dry.

Eldo with S11's. Not the best photo but a cool composition. Motel was three miles from my house. Closed now and the sign
was blown out by a storm, or it would be in my garage.

You'll have to wait for the gravel road shot. Inmate Jeff Munn and I rode together during the last few days and he has a shot of me on the 'Guzzi traveling down a local dirt road. Said he'd shoot me a copy. Forded a few puddles, too!
